Parola Zone problem reported on Arduino forum

Hi, I just want to let you know that I am playig around with the Parola_Zone_TimeMsg example, I changed it to 4 zones like this:

define MAX_DEVICES 32

... P.setZone(0, 0, 7); P.setZone(1, 8, 15); P.setFont(1, numeric7Seg); P.setZone(2, 16, 23); P.setZone(3, 24, 31);

P.displayZoneText(3, szTime, PA_CENTER, SPEED_TIME, PAUSE_TIME, PA_PRINT, PA_NO_EFFECT); P.displayZoneText(2, szMesg, PA_CENTER, SPEED_TIME, 0, PA_SCROLL_RIGHT, PA_SCROLL_RIGHT); P.displayZoneText(1, szTime, PA_CENTER, SPEED_TIME, PAUSE_TIME, PA_PRINT, PA_NO_EFFECT); P.displayZoneText(0, szMesg, PA_CENTER, SPEED_TIME, 0, PA_SCROLL_LEFT, PA_SCROLL_LEFT); ....

Interesting thing is this works (however, zone 2 stays blank, why ever...); at least there are no crashes and time display is updated in both zones 1 and 3. Parola_Zone_TimeMsg_mod.zip

Maybe this helps...

Greetings, Walter

I made my sketch as I intended. This one works with all 4 zones! I attach it for you, though it is not completely finished. BTW: why is "hPa" not displayed, but " a" instead? I did not find out so far.

Oops - forgot the attachment yesterday. Here it is.

Hello walterdkn! Were you able to solve your 'zone 2 blank' problem? I would like, with your permission, to use your code!

No similar issues reported.

Hi I have same problem with four zone. Buffer of data only have 2 zone data.My code is very complicate. I test walterdkn code and get same result.

[walterdkn]

Hi malekhosseini, in the meantime I reworked the code. This one works for me, a 4-line clock display (time, date, air pressure, temperature). You must take care of variable length in the arrays (e.g. monat[12][12]. I use an Arduino Mega for this, because with a Nano it didn't work good. Greets, walterdkn

Hi walterdkn Thank you. This is not my issues because i use ESP32 with 320k RAM.

[Dancopy]

Hello walterdkn 1) Could you post a video on youtube about what your code does and what components are you using? 2) I don't understand why you are using FastLED? Aren't you using the FC16_HW Matrix? Thank you

[Dancopy]

Waiting for an answer!

[walterdkn]

Hi Dancopy, my reply via email seems not to have reached you. So here is what I wrote and a link to a YT video at the end:

The clock has 60 neopixels for the display of seconds around the matrices. I use the following components:

• Arduino Mega
• 16x MAX7219 dot matrix displays, arranged in 4 lines with 4 displays each
• 60x WS2812 (12 stripes with 5 pixels each; however, single LEDs look much better since you can arrange them in a perfect circle; I made this in other projects)
• NEO-6M GPS module for receiving time and date; in the sketch the UTC time is converted to local time with daylight saving dates
• BME280 sensor for air pressure and temperature
• BH1750 light sensor for automatic dimming; however, dimming of the matrices is way limited, even with the lowest setting the display are very bright.
• 5V/2500mA wall plug; if you do not make use of full brightness of matrices and/or neopixels this is sufficient.

1st line: static display of time (hh:mm) 2nd line: running display of date (weekday, day, written month, year) 3rd line: static display of air pressure (in hPa) 4th line: static display of temperature (degrees celsius)

I hope this helps a bit. The arduino code is not yet optimized, but runs so far without errors.

Wow! Very cool your project, congratulations and thank you!
